IMPROVEMENT IN PhOVVS.

Specification forming part of Letters Patent No; 23,534., dated March 1,1859.

To all whom it may concern:

Be it known that I, JOHN M. WHITNEY, of

Bolton, county of Worcester, in the State of Massachusetts, haveinvented a new and useful Improvement in Holding Flows; and I do herebydeclare that the following is a full and exact description thereof,reference being bad to the accompanying drawings, and to the letters ofreference marked thereom' The nature of my invention consists inarranging with the plowshare and its beam an adjustable frame carrying arotating regulating-wheel, as hereinafter specified.

To enable those skilled to make and use my improved plow, I will proceedto describe its construction and operation, referring; by letters to theaccompanying drawings, forming part of this specification, and in which-Figure 1 represents a back elevation; Fig. 2, an elevation'on the landside, and Fig. 3 a top view of the same.

Similar letters denote the same parts in the different views.

I represents the mold-board, G the beam, and g the handles, of a plow ofordinary construction, and to which is attached by journalboxes B d onthe land side of the plow the adjustable swinging frame 0 D.-

E is auadjusting brace-rod, which is pivoted atone end to the rear sideof the frame piece 0, near its extremity, and secured in any desiredposition at its other end by a setscrew, F, passing through aslot insaid rod E and into the standard A.

. 7 His a rotary ground-wheel which travels on the land side of theplow.

From the foregoing description of the construction of my improved plowarrangement it will be understood to operate as follows: As the plow isstarted to form the furrow the wheel H, with its frame 0 D, on the landside of and sufficiently heavy to control the other parts of theapparatus, travels upon the ground and governs the run of the plow bycontrolling the angle at which the mold-board works, thus regulatingperfectly its operation and the depth of furrow. The run of the plow, itwill be seen, may be readily varied according to variable circumstancesunder which it may have to work by the adjustment up and down of thewheel H and its frame-work 0 D.

It will also be seen that the apparatus for regulating the operation ofthe plow in form-. ing the furrow, being abreast of the body of theplow, does not at all hinder the operator in turning the latter at theend of the furrow.

I am aware of wheels having been used in connection with a plow, and donot claim broadly any such device; but,

Having described the construction and opmy hand and seal this 11th dayof February,

JOHN M. WHITNEY. n SL1 Witnesses:
